Knowledge Graphs on the Web – an Overview Arxiv:2003.00719V3 [Cs
January 2020 Knowledge Graphs on the Web – an Overview Nicolas HEIST, Sven HERTLING, Daniel RINGLER, and Heiko PAULHEIM Data and Web Science Group, University of Mannheim, Germany Abstract. Knowledge Graphs are an emerging form of knowledge representation. While Google coined the term Knowledge Graph first and promoted it as a means to improve their search results, they are used in many applications today. In a knowl- edge graph, entities in the real world and/or a business domain (e.g., people, places, or events) are represented as nodes, which are connected by edges representing the relations between those entities. While companies such as Google, Microsoft, and Facebook have their own, non-public knowledge graphs, there is also a larger body of publicly available knowledge graphs, such as DBpedia or Wikidata. In this chap- ter, we provide an overview and comparison of those publicly available knowledge graphs, and give insights into their contents, size, coverage, and overlap. Keywords. Knowledge Graph, Linked Data, Semantic Web, Profiling 1. Introduction Knowledge Graphs are increasingly used as means to represent knowledge. Due to their versatile means of representation, they can be used to integrate different heterogeneous data sources, both within as well as across organizations. [8,9] Besides such domain-specific knowledge graphs which are typically developed for specific domains and/or use cases, there are also public, cross-domain knowledge graphs encoding common knowledge, such as DBpedia, Wikidata, or YAGO. [33] Such knowl- edge graphs may be used, e.g., for automatically enriching data with background knowl- arXiv:2003.00719v3 [cs.AI] 12 Mar 2020 edge to be used in knowledge-intensive downstream applications. -

Why Has AI Failed? and How Can It Succeed?
Why Has AI Failed? And How Can It Succeed? John F. Sowa VivoMind Research, LLC 10 May 2015 Extended version of slides for MICAI'14 ProblemsProblems andand ChallengesChallenges Early hopes for artificial intelligence have not been realized. Language understanding is more difficult than anyone thought. A three-year-old child is better able to learn, understand, and generate language than any current computer system. Tasks that are easy for many animals are impossible for the latest and greatest robots. Questions: ● Have we been using the right theories, tools, and techniques? ● Why haven’t these tools worked as well as we had hoped? ● What other methods might be more promising? ● What can research in neuroscience and psycholinguistics tell us? ● Can it suggest better ways of designing intelligent systems? 2 Early Days of Artificial Intelligence 1960: Hao Wang’s theorem prover took 7 minutes to prove all 378 FOL theorems of Principia Mathematica on an IBM 704 – much faster than two brilliant logicians, Whitehead and Russell. 1960: Emile Delavenay, in a book on machine translation: “While a great deal remains to be done, it can be stated without hesitation that the essential has already been accomplished.” 1965: Irving John Good, in speculations on the future of AI: “It is more probable than not that, within the twentieth century, an ultraintelligent machine will be built and that it will be the last invention that man need make.” 1968: Marvin Minsky, technical adviser for the movie 2001: “The HAL 9000 is a conservative estimate of the level of artificial intelligence in 2001.” 3 The Ultimate Understanding Engine Sentences uttered by a child named Laura before the age of 3. -

Wikipedia is the largest collaborative encyclopedia and is used as the source for DBpedia, a central dataset of the LOD cloud. Wikipedia contains numerous numerical measures on the entities it describes, as per the general character of the data it encompasses. The DBpedia In- formation Extraction Framework transforms semi-structured data from Wikipedia into structured RDF. However this extraction framework of- fers a limited support to handle measurement in Wikipedia. In this paper, we describe the automated process that enables the creation of the Chaudron dataset. We propose an alternative extraction to the tra- ditional mapping creation from Wikipedia dump, by also using the ren- dered HTML to avoid the template transclusion issue. -
Logic-Based Technologies for Intelligent Systems: State of the Art and Perspectives

Since logic-based approaches lay at the core of symbolic AI, summarizing their state of the art is of paramount importance now more than ever, in order to identify trends, benefits, key features, gaps, and limitations of the techniques proposed so far, as well as to identify promising research perspectives. Along this line, this paper provides an overview of logic-based approaches and technologies by sketching their evolution and pointing out their main application areas. Future perspectives for exploitation of logic-based technologies are discussed as well, in order to identify those research fields that deserve more attention, considering the areas that already exploit logic-based approaches as well as those that are more likely to adopt logic-based approaches in the future. -

Talking to Computers in Natural Language
feature Talking to Computers in Natural Language Natural language understanding is as old as computing itself, but recent advances in machine learning and the rising demand of natural-language interfaces make it a promising time to once again tackle the long-standing challenge.

This process of language understanding has so far been the sole privilege of humans. But the universality of computation, Aas formalized by Alan Turing in the early 1930s—which states that any computation could be done on a Turing machine—offers a tantalizing possibility that a computer could understand language as well. Later, Turing went on in his seminal 1950 article, “Computing Machinery and Intelligence,” to propose the now-famous Turing test—a bold and speculative method to evaluate cial intelligence at the time.

Conceptualization and Visual Knowledge Organization: a Survey of Ontology-Based Solutions
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Repository of the Academy's Library CONCEPTUALIZATION AND VISUAL KNOWLEDGE ORGANIZATION: A SURVEY OF ONTOLOGY-BASED SOLUTIONS A. Benedek1, G. Lajos2 1 Hungarian Academy of Sciences (HUNGARY) 2 WikiNizer (UNITED KINGDOM) Abstract Conceptualization and Visual Knowledge Organization are overlapping research areas of Intellect Augmentation with hot topics at their intersection which are enhanced by proliferating issues of ontology integration. Knowledge organization is more closely related to the content of concepts and to the actual knowledge items than taxonomic structures and ‘ontologies’ understood as “explicit specifications of a conceptualization” (Gruber). Yet, the alignment of the structure and relationship of knowledge items of a domain of interest require similar operations. We reconsider ontology-based approaches to collaborative conceptualization from the point of view of user interaction in the context of augmented visual knowledge organization. After considering several formal ontology based approaches, it is argued that co-evolving visualization of concepts are needed both at the object and meta-level to handle the social aspects of learning and knowledge work in the framework of an Exploratory Epistemology. Current systems tend to separate the conceptual level from the content, and the context of logical understanding from the intent and use of concepts. Besides, they usually consider the unification of individual contributions in a ubiquitous global representation. As opposed to this God's eye view we are exploring new alternatives that aim to provide Morphic-like live, tinkerable, in situ approaches to conceptualization and its visualization and to direct manipulation based ontology authoring capabilities.
